Benefits of technology
The patent is about a device that can filter and amplify signals from different networks using different frequencies. This allows for increased data throughput for multiple users and enables roaming without the need for multiple relays for each frequency. The device also provides power savings for devices communicating using non-mobile interfaces. Overall, the device improves data throughput and provides more efficient use of radio frequency hardware.
Problems solved by technology
One of the major challenges for mobile operators has been to overcome indoor penetration loss particularly in underserved areas of radio access.
Indoor penetration loss results in poor data quality, poor data transmission rates and high power requirements for transmission.
MBB often suffers from inferior data throughput and stability which makes it very challenging for mobile operators to provide effective MBB service to customers, especially to families and Small and Medium Enterprises (SMEs).
There are several limitations to this solution.
One limitation of indoor pico repeaters is that they can only amplify the radio signal of one operator because the repeater is set to a particular frequency band.
This may not be a problem in some scenarios; however it is particularly problematic in others.
For example, the repeater cannot be used to provide services to families where different family members subscribe to different operators and may all need stable signal.
Further, indoor pico repeaters are not appropriate for moving objects, such as ships or caravans, as amplification while roaming is not possible.
Unfortunately it is often the case that those areas having poor DSL quality are underserved areas of radio access, such as suburban and rural areas.
In these scenarios the indoor signals are weak and unstable and so the 3G or 4G cannot be used.
The degraded input signal will thus severely impact the Wi-Fi services.
This situation may also occur in good outdoor coverage areas where there is high penetration loss and interference, for example in high density, large buildings.

Embodiment Construction
[0031]In the following description, reference may be made to 3G and 4G and to particular standards. However, it should be understood that the present disclosure is not intended to be limited to any of these technologies. The present invention may also be applicable to a number of modes such as Time Division Duplex (TDD), Frequency Division Duplex (FDD), Time Division-Synchronous Code Division Multiple Access (TD-SCDMA), and High Speed Downlink Packet Access (HSDPA), among others.
[0032]While devices and apparatus are often referred to as “mobile” in the description, the term “mobile” should not be construed to require that a device will always be mobile merely that it has the capability of being in communication with a wireless telecommunications network which allows mobility. For instance, a PC terminal or a machine client that is never moved from a particular geographic location may in a sense still be considered mobile as it could be moved to a different location yet still access ...

The invention provides for an electronic apparatus for amplifying a plurality of different frequency bands of a wireless telecommunication signal. The apparatus comprises: a first antenna configured to receive a wireless communication signal; a filtering module configured to: receive an indication of a plurality of different frequency bands to be filtered; and, selectively filter the wireless telecommunication signal according to the received indication to form a filtered wireless telecommunication signal; a filter controller configured to provide the indication to the filtering module; and, an amplifier configured to amplify the filtered wireless communication signal.
Description
BACKGROUND[0001]Wireless indoor coverage is becoming increasingly important to mobile network operators. It has been estimated that by 2016 over 80% of global wireless data traffic will be generated indoors. One of the major challenges for mobile operators has been to overcome indoor penetration loss particularly in underserved areas of radio access. The situation is exacerbated by the deployment of 3G & 4G technology where high frequencies have been adopted which suffer more from indoor penetration loss than low frequencies. Indoor penetration loss results in poor data quality, poor data transmission rates and high power requirements for transmission.[0002]Typically there are two types of data services available to indoor users: the conventional digital subscriber line (DSL) and Wi-Fi router solution provided mainly by fixed line operators; and the Mobile Broadband (MBB) solution provided by mobile operators over 3G or 4G. MBB often suffers from inferior data throughput and stabili...
